This is also to give pain relief to the wound and invigorate blood stasis. Rubbing hot hands and then applying directly will make the stagnant blood and tissue fluid be digested and absorbed by the body, so if the body has redness or sprains, you can use safflower oil to treat them, but if there are skin cracks, bleeding and broken skin, you can’t use safflower oil to heal the wounds, otherwise it will intensify the pain.
